Note that in Python 3, a regular expression compiled from a :class:`str` has the ``re.UNICODE`` flag set. If it is undesirable to store this flag in a BSON regular expression, unset it first:: >>> pattern = re.compile('.*') >>> regex = Regex.from_native(pattern) >>> regex.flags ^= re.UNICODE >>> db.collection.insert({'pattern': regex}) :Parameters: - `regex`: A regular expression object from ``re.compile()``. .. warning:: Python regular expressions use a different syntax and different set of flags than MongoDB, which uses `PCRE`_. A regular expression retrieved from the server may not compile in Python, or may match a different set of strings in Python than when used in a MongoDB query. .. _PCRE: http://www.pcre.org/ z3regex must be a compiled regular expression, not %s)Ú isinstancerÚ TypeErrorÚtyperÚpatternr)ÚclsÚregexrrrÚ from_native.s   zRegex.from_nativercCs`t|ttfƒstdt|ƒƒ‚||_t|tƒr:t|ƒ|_n"t|t ƒrL||_ntdt|ƒƒ‚dS)apBSON regular expression data.
